Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The invention provides a kind of radial canal double heat exchanger as depicted in figs. 1 and 2, pad including bolt 1, nut 2, first
Sheet the 3, second pad the 4, first sealing gasket the 5, first flange the 6, second sealing gasket the 7, second flange 8, heat exchanger body top 9,
Three sealing gaskets 10, heat exchanger body bottom 11, arcuate socket sealing gasket 12, three-flange 13, induction tunnel 14, combustion air outlet
15, combustion air inlet 16, fume emission outlet 17 and the 4th flange 18, described hot device body upper part 9 is by the 4th flange 18
Connect and have induction tunnel 14, described 4th flange 18 to be provided with bolt 1, nut the 2, first pad the 3, second pad 4 and the first sealing
Pad 5, is provided with arcuate socket sealing gasket 12 inside the flange body of described 4th flange 18, described induction tunnel 14 is by three-flange 13
Connect and have heat exchanger body bottom 11, inside the flange body of described three-flange 13, be provided with the 3rd sealing gasket 10, described heat exchange
One end of device body lower part 11 is provided with combustion air outlet 15, and described combustion air inlet 16 is by the first flange 6 and heat exchanger
One middle side part of body upper part 9 connects, and described first sealing gasket 5 is located at combustion air inlet 16 and the junction of the first flange 6,
Described fume emission outlet 17 is connected with the heat exchanger body top 9 of its lower end by the second flange 8, described second flange 8
Be provided with the second sealing gasket 7 inside flange body, described heat exchanger body top 9 and heat exchanger body bottom 11 respectively by outer tube,
Finned tube and inner tube composition.
Operation principle: heat exchanger body top 9 and heat exchanger body lower part 11 be not by outer tube, finned tube and inner tube group
Becoming, the waste gas of discharge is through the bottom of heat exchanger, then the top to heat exchanger, and high-temp waste gas is discharged with fin tube layer through outer tube,
Finned tube absorbs the substantial amounts of heat of waste gas, and combustion air is entered in the inner tube on heat exchanger top by entrance, inner tube in being passed through again
Pipe preheats with fin tube layer, constantly enters heat exchanger lower end after combustion air preheating, and preheated air is in heat exchanger lower end
After inner tube and fin tube layer heat again, enter in the inner tube of lower end after heating, inner catheter be passed directly into induction tunnel 14, complete to help
The heating process of combustion air, is connected by induction tunnel 14 between heat exchanger with burner, and induction tunnel 14 is provided with burner junction
Little corrugated tube, can effectively prevent expansion and contraction that variations in temperature causes, and the first flange 6 connects combustion air inlet 16,
Second flange 8 connects fume emission outlet 17, and the 3rd sealing gasket 10 is and radial canal adpting flange, and combustion air outlet is for through adding
Combustion air outlet after heat, radial canal double heat exchanger is installed at " W " type radial canal top straight section, burner product exit, and with
This defines inside and outside two relatively independent passages for border, and the combustion product high temperature of outer tunnel conveying radiation pipe burner tip gives up
Gas, amount of heat, when flowing through heat exchanger and being outside, is transmitted to heat exchanger by the outer spinal plate of Fin Mustetus manazo shape put outward by high-temp waste gas,
Make EGT be greatly lowered simultaneously；Internal channel then transmits combustion air, and the combustion air being in room temperature is entered by cold wind mouth
Heat exchanger, transmits in the inside tube of heat exchanger exit to the inside tube of lower end heat exchanger, finally leads to combustion air inlet, enter
Airduct and exhaustor shift to install, and extend the time of cold and hot exchange, add its heat exchange area, are effectively caused by combustion air
The position of waste gas discharge port, takes full advantage of the waste heat of the high-temp waste gas of discharge.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
